Up to recently, I would have said a hearty amen. However, about 2 weeks ago now I decided to completely cut out caffeine out of my diet and switched over to naturally caffeine free herbal teas. I gotta say, I feel more alert & awake throughout the day than I did before (on a typical work day I'd have at least 4 or 5 cups of coffee).

Whether or not I make this a permanent change, it sure has reshaped my understanding of my "need" for coffee.
